Metatext

Generally this encompasses the same kinds of ideas as Tim Berners-Lee's Semantic Web project, but the Tunes philosophy makes for a qualitatively different approach. Mainly, by not relying on the least common denominator of development tools, the typewriter-style text editing context, the issues with identity and ontology are more relevant to the actual domains than their representations in XML-based formats. Furthermore, a finer grain of referencing is possible due to the manner in which objects should be (de/re-)composable within Tunes semantics.

(Feel free to add comments to refine this idea or categorize approaches.)
